He has been described as the "father of the fertilizer industry" for his emphasis on nitrogen and trace minerals as essential plant nutrients, and his formulation of the law of the minimum, which described how plant growth relied on the scarcest nutrient resource, rather than the total amount of resources available.

Having determined to make chemistry his profession, at the age of fifteen he entered the shop of an apothecary at Appenheim, near Darmstadt, but he soon found how great is the difference between practical pharmacy and scientific chemistry, and the explosions and other incidents that accompanied his private efforts to increase his chemical knowledge disposed his master to view without regret his departure at the end of ten months. そのため、「農芸化学の父」とも称される。 応用化学においては、植物の生育に関する窒素・リン酸・カリウムの三要素説、リービッヒの最小律などを提唱し、これに基づいて化学肥料を作った。 Ein Jahr darauf folgte die Berufung zum ordentlichen Professor. In animal physiology, he set himself to trace out the operation of determinate chemical and physical laws in the maintenance of life and health. 이 때 생성물로 얻어진 물과 이산화탄소는 무생물계에서 찾아 볼 수 있는 물이나 이산화탄소와 똑같다. In regard to methods and apparatus, mention should be made of his improvements in the technique of organic analysis, his plan for determining the natural alkaloids and for ascertaining the molecular weights of organic bases by means of their chloro-platinates, his process for determining the quantity of urea in a solution-the first step towards the introduction of precise chemical methods into practical medicine-and his invention of the simple form of condenser known in every laboratory. 예컨대 글루코오스는 1747년에 건포도에서 처음 분리되었고, 1838년에 Jean Dumas 가 '달다'라는 뜻의 glycos로부터 glucose라고 명명했지만, 구조가 밝혀진 것은 19세기 에밀 피셔 Emil Fischer, 1902년 노벨 화학상 에 의해서였다.

The sciences begin with the substance itself, then come just ideas, and lastly, mathematics are called in, and with the aid of numbers, complete the work.

ほかにも、クロロホルム、クロラール、アルデヒドなどをはじめ多くの有機化合物を発見している。 The Letters contained in this little Volume embrace some of the most important points of the science of Chemistry, in their application to Natural Philosophy, Physiology, Agriculture, and Commerce.

Dabei orientierte er sich am trommsdorffschen Vorbild in Erfurt.

우리나라가 중화학공업을 통해 성장과 식량의 자급자족을 이루어낸 1960, 70년대에 비료 공장은 중요한 역할을 했다.

지금도 고등학교 교과서에 나오는 탄소와 수소의 원소분석 방법은 리비히가 1830년대에 발전시킨 것이다.

In 1832 he published, jointly with Wohler, one of the most famous papers in the history of chemistry, that on the oil of bitter almonds benzaldehyde , wherein it was shown that the radicle benzoyl might be regarded as forming an unchanging constituent of a long series of compounds obtained from oil of bitter almonds, throughout which it behaved like an element.
